Tuning of spinel magnesium ferrite nanoparticles with enhanced magnetic properties

Antibacterial properties of spinel ferrite nanoparticles

This book chapter is organized into four major parts. Firstly, it will cover an introduction of using spinel ferrite nanoparticles in biomedical applications, including the antibacterial properties. The second part will provide an overview of the structure and magnetism of spinel ferrites. The third part will focus on the preparation of cobalt ferrite and transition metal substituted cobalt fer...

Crystalization in Spinel Ferrite Nanoparticles

The enhanced interest of the researchers in nanoobjects is due to the discovery of unusual physical and chemical properties of these objects, which is related to manifestation of so-called ‘quantum size effects‘. These arise in the case where the size of the system is commensurable with the de-Brogli wavelengths of the electrons, phonons or excitons propagating in them.A key reason for the chan...

Effect of cobalt on structural, microstructural and magnetic properties of magnesium-zinc ferrite nanoparticles

Mg0.5-xCoxZnFe2O4 ferrite nanostructures with various amounts of Co2+ substitution (x= 0, 0.05, 0.10, 0.15) were prepared using a simple and inexpensive sol-gel method sol-gel route. Structural, microstructural and magnetic properties of the prepared powders were investigated by x-ray diffraction (XRD), Fourier transform infrared (FT-IR), field emission- scanning electron microscopy (FE-SEM), X...

Structural, magnetic, and magnetoelastic properties of magnesium substituted cobalt ferrite

An investigation on synthesis and magnetic properties of nanoparticles of Cobalt Ferrite coated with SiO2

SiO2-coated Cobalt Ferrite (CoFe2O4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of CoFe2O4 nanoparticles in co-precipitation. The effects of SiO2coating on the magnetic properties of CoFe2O4 nanoparticles were investigated. The structural, morphological and magne...
